Abstract (en)
[origin: EP2388533A1] The installation has a pump (6) provoking circulation of a coolant (2) between a heat energy producing unit (3) e.g. solar collector, and a balloon of a hot water reservoir (1). A check valve (4) is connected in bypass on a return channel (52), where the check valve is connected to a drain tank (6) using an air channel (56) for circulation of air. The channel is provided with an overpressure generating unit (9) e.g. compressor, generating overpressure at the level of the check valve. An independent claim is also included for a method for improving a water heater installation.
